Hi John, A bit more information on my testing without luasocket. I removed all the existing DLLs and deployed your lua.exe, wx.lua and wxlua_lua_shared-wx28mswu-2.8.12.dll. When I start my app, it crashes immediately (without any error message) with this report: Problem Event Name: APPCRASH Application Name: lua.exe Application Version: 0.0.0.0 Application Timestamp: 4fed3948 Fault Module Name: wxlua_lua_shared-wx28mswu-2.8.12.dll Fault Module Version: 0.0.0.0 Fault Module Timestamp: 4fed3947 Exception Code: c0000005 Exception Offset: 0000d8b2 OS Version: 6.0.6002.2.2.0.256.6 Locale ID: 1033 Additional Information 1: fd00 Additional Information 2: ea6f5fe8924aaa756324d57f87834160 Additional Information 3: fd00 Additional Information 4: ea6f5fe8924aaa756324d57f87834160 If I start a bit simpler version, it does show the editor window, but when I close the app (without doing anything else), it crashes with another crash report: Problem Event Name: APPCRASH Application Name: lua.exe Application Version: 0.0.0.0 Application Timestamp: 4fed3948 Fault Module Name: lua.exe Fault Module Version: 0.0.0.0 Fault Module Timestamp: 4fed3948 Exception Code: c0000005 Exception Offset: 00007c52 OS Version: 6.0.6002.2.2.0.256.6 Locale ID: 1033 Additional Information 1: fd00 Additional Information 2: ea6f5fe8924aaa756324d57f87834160 Additional Information 3: fd00 Additional Information 4: ea6f5fe8924aaa756324d57f87834160 Both seem to trigger the same error, just at different addresses. I don't have any additional information unfortunately, but please let me know if there is something I can try to assist in troubleshooting. Paul.
